Polini Corsa is the most powerful cast iron cylinder kit, from the market-leading Italian manufacturer. The kit is very similar to the Polini Sport, but with its larger ports and somewhat higher performance, is a good offer for a fast everyday cylinder kit. Due to the somewhat higher performance, min. 17.5mm carburetor. A long-threaded spark plug must be used for this cylinder. The kit is delivered complete incl. gaskets, piston rings, etc.
